Regulation method for enhancing sugar content of southern facility grape fruits

Abstract

The invention discloses a regulation method for enhancing the sugar content of southern facility grape fruits. The regulation method includes ethanol spraying measures, atmospheric humidity control measures, soil moisture control measures, temperature control measures, conventional light control measures and picking measures. The regulation method is good in sugar accumulation enhancing effect, and through the adopting of the regulation method, the sugar accumulation of southern facility grapes can be effectively increased(by more than 15%), and the yield of the grapes can be enhanced (by 10%); the regulation method is strong in operability; ethanol is a common material, is low in price, safe, environment-friendly, non-toxic and harmless, can inhibit the breathing of leaves, especially fruits, and can accelerate photosynthetic rate; through the adjusting of meteorological factors, the purpose of adjusting the sugar content of grape fruits can be further achieved; the regulation methodis simple in operation; and compared with other methods, the regulation method is low in cost, good in effect and suitable for the planting and production of southern facility table grapes.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a control method for increasing the sugar content of southern facility grapes. Background technique [0002] Grape (Vitis vinifera L.) is a fruit tree with the largest cultivated area in the world. To a large extent, the type and content of sugar in the fruit determine the quality of the grape. The protected cultivation area of ​​grapes in my country has reached 23,000 hm 2 , ranking first in the world. In recent years, the protected cultivation of grapes in the south has developed rapidly, and the protected cultivation area accounts for more than 65%. However, the sweetness of the same variety of grapes in Northwest my country is often higher than that in the South. Because grapes like high temperature difference between day and night, the southern climate often reduces the sugar content and affects the quality of grapes. [0003] Climatic conditions are...
